FLAGSTAFF, Ariz. (AP) -- Strong winds were expected Thursday at a 10-square-mile blaze just west of Prescott that could cause the inferno to grow even more and ground support aircraft.

More than 600 firefighters worked to build an indirect fire line on the east and west flanks of the blaze in Arizona's Prescott National Forest. Homes in the subdivisions north of the fire were assessed and prepped with sprinklers for protection.

Still, the Doce Fire had moved into people's backyards and forced the evacuation of hundreds of homes. However, no structures have been reported lost.
